Supply Chain Level 0: Grinding Tractors to a Halt – Sick Codes – ESW #281

Sick Codes hacked all four John Deere Telematics Gateway’s, and the John Deere Gen4 Series Display. Without those, it’s “just a tractor.” However, this is Critical Infrastructure. In fact, without Tractors, Combines & Implements: farmers cannot plant, spray or harvest. No raw materials == no food & alcohol. You will see how long I persisted over multiple months, to gain access and was able to hack these devices to the absolute binary core, warts & all. What was the bounty? Source Code, Root File Systems, FPGA compiled binaries, the works. Agricultural Security is a serious issue. Multiple ransomware attacks last year showed exactly how destructive attacks on Food & Agriculture are, and how fragile the supply chain is.
